InitilaContext instantiation error

[javier_arrieta]

Hi,

Whenever I try to create an initialcontext my jboss/tomcat distro (2.4.4) throws the following exception.

javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory. Root exception is
java.lang.ClassCastException: org.jnp.interfaces.NamingContextFactory
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:659)

I tried specifying the properties explicitly also
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
h.put(Context.PROVIDER_URL, "localhost:1099");
h.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

with no result

Any guess appreciated. Thanx in advance

Javier,
Dumb question, but are you passing the properties object ("h" in you're example) to InitialContext constructor?

like...

InitialContext iCtx = new InitialContext(h);

Otherwise you'll need to set these pros via System.setProperty() or
-D propertyname=value on command line.

Yes, of course I passed the Properties to the constructor...

Any other guess?

PS: Thnx anyway Mike

We use the following settings
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL ,"jnp://localhost:1099");
We don't use Context.URL_PKG_PREFIXES setting.

Hope this Helps

Hola Javier,

Are you using winXP and jdk1.4.0???

I have a friend with the same problem and the only different between my config and his is that he's using winXP.

When i Instantiate the InitialContext a only do this:

Context initial = new InitialContext ();

no propierties, nothing, th jndi.propierties should be in your classpath, nothing else.

Please, tell me if you are using winxp and jdk1.4.0 becouse maybe is a bug.

Regards, Enrique.

No, Enrique. I'm using Sun's jdk1.3.1_02 in a win2k machine. And i've also (my first tries) used the no-properties constructor with the same results.

Th most shocking issue is the ClassCastException error wrapped in a NamingException

Thanx anyway

Hola Javi,

We find the error¡¡¡

In our case the problem was that jndi.jar was inside the webapp (war file) in the lib directory. The problem was in our ANTs files.

When we correct it, the app was ok.

So i suspect that you have a similar problem, you are trying to cast a javax.naming.NoInitialContextException to a class different of org.jnp.interfaces.NamingContextFactory becouse in your CLASSPATH you have another jndi classess.

Hope That Help

Enrique.
